Sulfosulfuron

Type: Herbicide

Mode of Action: Inhibiting the enzyme acetolactate synthase (ALS)

Common Product Names: Outrider & Certainty

What is it?

Sulfosulfuron is a systemic herbicide, meaning it is absorbed and translocated throughout the plant, ensuring comprehensive weed control. It is primarily used in agricultural and turf settings. In agriculture it is used particularly for the management of weeds in cereal crops like wheat and barley. Sulfosulfuron is also effective in non-crop areas, such as industrial sites and turf management to remove johnsongrass and nutsedge.

How does it work?

Once applied, sulfosulfuron is absorbed by the foliage and roots of the target weeds. It then moves within the plant to meristematic regions, the growing points, where it inhibits the ALS enzyme. This inhibition prevents the production of essential amino acids, leading to the cessation of cell division and growth, chlorosis (yellowing of leaves), and ultimately plant death. . Consequently, the weeds gradually wilt and die, typically within a few weeks of application.

Benefits

  • Selective: One of the key benefits of sulfosulfuron is its selectivity. It targets a wide range of broadleaf weeds and grasses without harming the desirable crops, making it ideal for use in cereals and other sensitive plants.
  • Low Use Rates: Sulfosulfuron is highly effective at low application rates. This not only makes it cost-effective but also minimizes the environmental impact by reducing the amount of chemical needed for effective weed control.
  • Residual Activity: It continues to control weeds for an extended period after application. This long-lasting effect helps in maintaining a weed-free environment for the crops throughout critical growth stages.
